なければならない。 Conventionally, when gold potassium cyanide was produced by electrolysis, a plate-shaped gold ingot was used as an anode, but the plate-shaped gold ingot was consumed as electrolysis progressed, reducing the surface area of the anode. Either the current conditions for electrolysis were controlled according to the depletion, or the plate-shaped gold ingot was replaced when the surface area of the anode decreased to a certain extent. There is also a method of producing gold potassium cyanide by electrolytic method by placing gold powder, grains, etc. in an insoluble basket and hanging it vertically in a tank and using it as an anode, but as the electrolysis progresses, it is consumed and the basket Gold powder, grains, etc. settle within the anode, reducing the surface area of the anode, so gold powder, grains, etc. must be replenished according to the amount of consumption.

ある。 The present invention was made in order to solve this problem, and even if the anode such as gold powder or grains is consumed, the effective area as an anode can be kept approximately constant, and the current conditions for electrolysis can be controlled. The object of the present invention is to provide a method capable of producing potassium gold cyanide without the need for the production of potassium gold cyanide.

作業性、生産性が向上する。 In the method for producing potassium gold cyanide of the present invention, as the electrolysis progresses, the gold powder, grains, etc. that serve as the anode dispersed on the horizontal electrode are consumed, but the planar area of the gold powder remains almost unchanged. Therefore, the effective area of the anode can be kept substantially constant, and the current conditions for electrolysis can be kept constant. In particular, if gold powder, grains, etc. are replenished and dispersed on the electrode as electrolysis progresses, or if a predetermined amount is supplied, the effective area as an anode can be continuously maintained at a substantially constant level, and the gold powder on the electrode can be kept constant. By applying vibration to the particles as electrolysis progresses, or by smoothing the surface of the gold powder, particles, etc. with a rotating rod, the distribution of the gold powder, particles, etc. on the electrode will be uniform, and the effective effectiveness of the anode will be improved. The area can be kept constant continuously, and the current conditions for electrolysis can also be kept constant. In this way, even if the anode such as gold powder or grains is consumed, there is no need to control the electrolytic current conditions.
Improves work efficiency and productivity.
